Nudity is a state of being in which a human is not wearing clothing or specifically is not covering the genitals. In some societies, partial nudity is defined as not covering other parts of the body that are deemed to be sexual. Worldwide, current social norms vary from banning nudity except in complete privacy to the acceptance of public nudity as a natural human state.
Nakedness, or the loss of body fur, was one of the physical characteristics that marked the biological evolution of modern humans from their hominini ancestors. Adaptations related to hairlessness contributed to the increase in brain size, bipedalism, and the variation in human skin color. Although often used interchangeably, "naked" and "nude" are also used to distinguish between the various meanings of being unclothed.
It is generally accepted that the widespread adoption of clothing occurred as people migrated to climates that required protection from the elements, or when ice age climate change required adaptation to cold. Humans that remained in tropical climates continued to be naked, or minimally clothed. While estimates vary, for at least 90,000 years anatomically modern humans wore no clothing, the invention of which was part of the transition from being not only anatomically but behaviorally modern. As societies developed from being hunter-gatherers to being agrarian, clothing became part of cultural evolution as individuals and groups became differentiated by status and class. In early civilizations such as Egypt; slaves, children, and others with low status often continued to be naked. (Full article...)
Nudity is one of the physiological characteristics of humans, who alone among primates evolved to be effectively hairless. Human sexuality includes the physiological, psychological, and social aspects of sexual feelings and behaviors. In many societies, a strong link between nudity and sexuality is taken for granted. Other societies maintain their traditional practices of being completely or partially naked in social as well as private situations, such as going to a beach or spa. The meaning of nudity and sexuality remains ambivalent, often leading to cultural misunderstandings and psychological problems. (Full article...)

Ariadne Asleep on the Island of Naxos (1808–1812) by John Vanderlyn. The painting was initially considered too sexual for display in the Pennsylvania Academy of the Fine Arts. "Although nudity in art was publicly protested by Americans, Vanderlyn observed that they would pay to see pictures of which they disapproved."
